Novel reactor for electrically assisted photocatalysis
摘要：
设计了一种新型电助光催化氧化反应器——内外同心圆柱形反应器。考察了直流电压、电极布置方式、水力停留时间、反应器高度和半径等因素对反应器的影响，并分析了影响反应器设计的结构因子。研究表明，该反应器可有效降解苯甲酰胺。在本研究中，当反应器半径为3.5 cm，停留时间为120 min，直流电压为1.016 V时，苯甲酰胺的稳定去除率可达95%。

Abstract：
Designs a new type EAP reactor which arranging the anode and cathode as two concentric cylinders with different radius. Analyses the influence of volts d. c., the arrangement of electrodes, the hydraulic detention time(HRT), the reactor radius and its height, and the structural factor. The results show that the new type reactor could degrade benzamide efficiently. The removal efficiency of benzamide can be as high as 95% when the radius of the EAP reactor is 3.5 centimeter，the HRT is 120 minutes and the volts d. c. is 1.016 volts.
